Im really considering buying myself the new iPad. Probably gonna go with the 32 gb wifi, not the wifi + cellular. Is everyone happy with theirs? I really only use my 15" macbook pro (circa 2006) to go on the internet, listen to music, and store files and pictures. Ill be doing the same on the Ipad. But If I only get the Wifi, will I be able to go on Instagram and text people? Any tips or suggestions for a first time buyer?
